【摘要】 本文以乙醇为溶剂合成了稀土元素(RE=Tb,Eu,Sm)与对硝基苯乙酸(HL)、2,2′-联吡啶(bipy)的三元固体配合物,通过元素分析等手段确定了稀土配合物的组成为REL3bipy.2H2O,用红外光谱、紫外光谱、热分析对该类配合物的结构与性质进行了表征,红外光谱表明配体以-COO-的形式与中心离子配位,同时这一点也被自由配体和配合物的UV谱所证实。更多还原

【Abstract】 The ternary solid rare-earth complexes were synthesized using paranitrobenzoic acid(HL),2,2′-bipyridine(bipy) and rare-earthin in ethanol solvent.Their compositions were confirmed to be REL-3·bipy·nH-2O(n=2,3;RE=Tb,Eu,Sm) by the element analysis.The structures and properties of the complexes were characterized by infrared and ultraviolet absorption spectra and DTA-TGA relatively.The IR spectra show the ligands coordinate to central ion in-COO-style.This was also verified by comparison of the UV spectra of the free ligand and the complexes.更多还原
